"Adolar" (♥ this series and the dog + adolar's fantastic rubberband space-ship. I always wanted to go on the roof of my granny's house and try if it works with a matrace too. guess what: I did it with my best friend, but it didn't work :-( I figured out, it must be jinxed because of my friend, so I decided to do it alone another time. but I was too scared to really pull it off alone at night on the spooky, dirty roof all by myself, so I never flew to mars, or the planet of the mermaids, the "backwards" planet or to "prehistoric planet" :-)))) )
